NBRC Mock TMC Exam 2024-2025 WITH QUESTIONS AND
VERIFIED ANSWERS GRADED A+
After the RespiratoryTherapist sets up a nonrebreathing mask on a patientat a flow
rate of 10 L/min, the reservoir bag collapses before the patient finishes inspiring.
The RT should do which of the following?
A. Change to a simple mask at a flow rate of 10 L/min
B. Remove the one-way valve from the exhalation port.
C. Place the patient on continuous positive airway pressure (CPAP)
D. Increase the flow rate to 15 L/min: D. Increase the flow rate to 15 L/min
A patient with carbon monoxide (CO) poisoning can best be treated withwhich of
the followingtherapies?
A. Nasal Cannula at 6 L/min
B.Simple O2 mask at 10 L/min
C. CPAP and 60% O2
D. Nonrebreathing mask: D. Nonrebreathing mask
The following blood gas levels have been obtained from a patient using a60%
aerosol mask.
pH: 7.47
PaCO2: 31 mmHg
PaO2: 58 mmHg
What should the RT recommend at this time?
A. Place the patient on CPAP
B. Increase the O2 to 70%
C. Intubate and place the patient on mechanical ventilation
D. Change to a nonrebreathing mask: A. Place the patient on CPAP
, Given the following data, what is the patient's total arterial O2 content?
pH: 7.41
PaCO2: 37 mmHg
PaO2: 88 mmHg
HCO3: 26 mEq/L
SaO2: 95%
Hb: 14 g/dL
A. 12 mL/dL
B. 14 mL/dL
C. 16 mL/dL
D. 18 mL/dL: (Hb x 1.36 x SaO2) + (0.003 x PaO2)(14 x 1.36 x0.95) + (0.003 x 88)
18.088 + 0.264
= 18.352
Answer: D. 18 mL/dL
While assisting with a bronchoscopy, you note that the physician is having

A. Pneumothorax
B. Tracheomalacia
C. Laryngospasm
D. Pulmonary hemorrhage: C. Laryngospasm
After a bronchoscopy, the RT notes that it is taking more ventilator pressure to
ventilate the patient's lungs than before the procedure. Thiscould be caused by
which of the following?
I. Bronchospasm
II. Pneumothorax
III. Hypoxemia
IV. Pulmonary hemorrhage
A. 1 and 2 only
